Resistin is a peptide hormone belonging to the class of cysteine-rich secreted proteins termed the RELM family, and is also described as ADSF (Adipose Tissue-Specific Secretory Factor) and FIZZ3 (Found in Inflammatory Zone). Resistin impairs glucose tolerance and insulin action in mice and also inhibits adipogenesis of murine 3T3-L1 cells. Therefore, resistin has been proposed as an adipocyte secreted factor linking obesity and type 2 diabetes. This Enzyme Immunometric Assay (EIA) is based on a double-antibody sandwich technique for quantification of rat resistin. [Bertin Catalog No. A05179]
